Diagnostic dilemmasAn uncommon source of mitral valve regurgitation
Section snippets
Diagnosis: cleft mitral valve
In this case, the cleft mitral valve is associated with an ostium primum ASD. This patient represents the mildest form of an atrioventricular (AV) canal defect with 2 separate AV valve orifices, a small ostium primum ASD, and no defect at the level of the ventricles. The first echocardiogram (Fig 1) is an ME 4-chamber view, which shows a defect in the anterior leaflet of the mitral valve (MV). In this particular patient, there are 2 separate AV valve annuli in association with an ostium primum

Unexpected Mitral Regurgitation During Coronary Artery Bypass Graft Surgery: The Multidisciplinary Management of a Mitral Valve Cleft
2018, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :This congenital form of MR can be differentiated from normal leaflet defects such as a scallop in that the tissue defect of a cleft typically extends completely to the annulus (see Fig 2).5 Mitral valve clefts affect the anterior mitral leaflet more commonly than the posterior leaflet and may be associated with additional congenital abnormalities such as atrial septal defects (Fig 3) and aberrant chordal attachments of the mitral valve.4–8 These aberrant chordal attachments may be associated with a parachute mitral valve when they attach predominantly to a single papillary muscle and left ventricular tract obstruction when they attach to the ventricular septum.4–8
